Now that the
trailer for "The Day of the Doctor" is out, it's time for
"Doctor Who" fans to relive it again and again. Two fan favorite Doctors (
Matt Smith and
David Tennant) are meeting up and things are going to get pretty entertaining.

Zap2it has taken some of the best moments from the trailer and turned them into animated GIFs for your consumption. What does Tennant think about Smith's TARDIS? How about that epic sonic screwdriver showdown?

Check out the GIFs below and feel free to stare at them for hours, you know you want to.
